		var (_p1, _p2) = RuntimeInformation.IsOSPlatform (OSPlatform.Linux)

			RedirectStandardError = true

		Environment.Exit (0);
	});

I use this code to restart the server under Linux, the effect is always, the first time to create successfully and exit itself, the second time (new process) to create failed and exit itself, what is the cause of this problem, how to fix?
